Jerks backward uncontrollably

My 1998 Corona Exiv rolls for a bit when in reverse, then stops suddenly even though the accelerator is still depressed. It eventually jerks backward uncontrollably for a few meters. Then responds to the brake pedal being depressed. This problem doesn’t occur when the car is in Drive.

This sounds to me like a transmission related issue. The first thing to check would be the transmission fluid level.

If the fluid level is low, top it off and retest several times. While checking the fluid if the color appears dark or burnt looking it may be too late. Burnt color fluid is an indication of worn internal material.

I am having a few issues that popped up all at once. I got a few recalls fixed on the car march 30th for the spiral cable and power window something? And then finally the airbag recall fixed a few weeks ago. The problem I’m having, car has 60 thousand miles on it. I was driving it and all of a sudden, the speedometer, tachometer stopped working. Along with those issues the airbag light, abs light, power steering light, and the break light came on all at once. Ive taken it in 3 separate times to different shops and keep getting the run around about it. They cant read it. Either the reader they used is too old and doesn’t read our car or its the actual car. I believe its either the instrument cluster and/or the speed sensor. However, I’m unsure of what would cause the airbag light to come on and am coming to the conclusion that the spiral cable wiring replaced during the recall wasn’t done properly. I cant think of any other reason why that would happen. I need to get it fixed before we ship it on order. The problem with that is we are oconus and the servco Toyota has a stand by of literally weeks. orrrr I have to make an appointment a month and half out?! and needs shipped end of this month. any ideas would be much appreciated!!! its a great car. never had any isssues the 2 years weve had it till now. would love to keep it especially since it has such low miles.

Need to get it into a facility that has the updated equipment that is able to read the codes. Or you could purchase your own scan tool and do it yourself. Without the codes you would just be throwing money at it. If you are concerned with the previous work you may want to contact them and allow them the chance to take a look at it.

I have replaced the thermostat and gasket and I am trying to replace the water outlet gasket also. There is a metal bar across the housing of the water outlet that is the L and R fuel line for the injectors. I need to be able to move that line in order to get to the housing and replace the gasket. How can I do that?

REMOVE DELIVERY PIPES AND INJECTORS

Be careful not to drop the injectors when removing the delivery pipes.

Pay attention to put any hung load on the injector to and from the side direction.

Wiper motor problem

I have a 2004 Avalon XLS with wiper motor problem. The intermittent speed does not work. I have had the motor replaced 4 times and the problem occurs with each motor. Oddly, the replacement motor number 2 would not work intermittently at first but after several weeks of use it just started to work. Then several months later the motor just stopped working. The repair shop replaced the motor again two more time but I still have no intermittent speed.

Here is another twist, when I last had to use the wipers, they occasionally would not shut off until I turned off the car. When I I turned the controls on the wiper arm switch to off but it kept running. Should I return it again to the repair shop? Is the problem is not with the motor but the switch or some other controller?

I would think the problem would be in the combination switch if not in the motor. It is about the only thing left other than the wiring harness itself.

Its having trouble starting at times, the battery & oil light are one, it also turns off when stopped or slowing.

I would start with the battery light. This is an indication of the alternator no longer charging the battery. This could give you a weak battery situation and cause difficulty starting. Have the alternator tested and fully charge the battery. Of course I am assuming you have already confirmed the oil level is sufficient.
